Craaaaaaaaap. I've tried looking for a 9002 and couldn't find one ! And are you sure about quietness ? Everyone I've seen who's owned a CAD 50 Elite says its dead quiet. Oh, did you try fitting it in the first chamber without the mounting option ? I've already ordered it.
The 9002 is still out there. I didn't try removing the bracket because it needs it to be positioned at the right height. This skimmer isn't tall enough to sit on the bottom and not be too deep. You might be able to remove the bracket and use some egg crate or something to keep the skimmer up at the right height.
